Effect of deprivation on weight gain in infancy

Weights were retrieved from child health records for an annual cohort of 3418 children, aged 18–30 months, to explore the relationship between deprivation and weight gain. Their level of deprivation was classified, using census data for their area of residence, as affluent (11%), intermediate (69%) or deprived (20%). Children from deprived areas were smaller at all ages with a widening gap: by one year of age, they were three times as likely as affluent children to be below the third centile for weight. The thrive index, a measure of the degree of centile shift, showed a slight gain over the first year in affluent and intermediate children, while in deprived children it decreased ( p = 0.001). Deprived children were 2.2 times more likely than intermediate children to have failure to thrive, as manifest by subnormal thrive index values ( p = 0.00008). Unexpectedly, children from affluent areas also showed slightly increased rates. We suggest that this may be explained by higher rates of breast feeding in affluent areas.     

Uterine leiomyomas in the infertile patient: preoperative localization with MR imaging versus US and hysterosalpingography

Eleven women with a history of infertility and uterine leiomyomas underwent magnetic resonance (MR) imaging of the pelvis prior to myomectomy. Nine also underwent preoperative pelvic ultrasonography (US), and ten underwent hysterosalpingography. All studies were interpreted prospectively by independent observers. With each imaging modality, the location (one of 11 anatomic segments), size, and appearance of detected uterine leiomyomas were determined and compared with surgical and histologic findings. Among the nine patients who underwent both MR and US, the sensitivity (85%) and accuracy (94%) of MR imaging for abnormal segments was significantly better than that of US (sensitivity = 69%, P = .015; accuracy = 87%, P = .043). For the ten patients who underwent both MR and hysterosalpingography, the sensitivity (91%) and accuracy (96%) of MR imaging was better than that of hysterosalpingography (sensitivity = 18%, P = .0005; accuracy = 72%, P = .0005). The specificities of the three modalities did not significantly differ (100%, 97%, and 98% for MR, US, and hysterosalpingography, respectively). These data suggest that MR imaging is superior to US or hysterosalpingography for preoperatively locating uterine leiomyomas.     

Elective intestinal operations in infants and children without mechanical bowel preparation: a pilot study

Background/Purpose

Preoperative mechanical bowel preparation (MBP) for elective intestinal operations has been a long accepted practice. However, MBP is often unpleasant and time-consuming for patients, and clinical trials in adults have not shown improved outcomes. We conducted this pilot study to test whether omitting MBP before elective intestinal operations in infants and children would increase the risk of infectious or anastomotic complications.

Methods

Retrospective review was performed of 143 patients who had an elective colon or distal small bowel procedure performed at our children's hospital between 1990 and 2003.

Results

Thirty-three patients (No PREP) were managed by a single surgeon who routinely omitted MBP, whereas another 110 patients (PREP) were prepared with enemas, laxatives, or both. Both groups received 24 hours of preoperative dietary restriction to clear liquids and perioperative parenteral antibiotics. The No PREP group had one anastomotic leak and no wound infections, whereas the PREP group had 2 anastomotic leaks and 1 wound infection (P = .58). These results occurred despite greater duration of antibiotic therapy and incidence of delayed wound closures in the PREP group.

Conclusion

The results of this pilot study suggest that omitting MBP before elective intestinal operations in infants and children carries no increased risk of infectious or anastomotic complications. Eliminating MBP may reduce health care costs and inconvenience to patients. These findings warrant a large, prospective, randomized clinical trial to validate our findings and to investigate further the necessity of MBP in the pediatric population.     

Cardiac MRI in Congenital Heart Disease – Our Experience

A significant recent advance that has occurred world over in the continuously evolving field of Magnetic Resonance Imaging (MRI) practice is the introduction of Cardiac applications. Cardiac MRI has moved to the centre stage of clinical management strategy by non-invasively imaging the structure as well as function of the heart. It has a wide range of specific applications such as delineation of morphological anatomy, quantification of flow and pressure across cardiac valve dysfunction, evaluation of myocardial function, assessment of infarcts, mapping coronary arteries and so on. Evaluation of congenital heart disease (CHD) is an important application of Cardiac MRI since the morphological details of chambers, septum, defects and anomalous connections are depicted accurately. Besides, flow information across valves, chambers, outflow tracts and shunts are also provided. This article describes our experience in the use of cardiac MRI in congenital heart disease.Key Words: Cardiac MRI, Congenital heart disease, Cyanotic and Acyanotic heart disease     

Indications for revascularization in patients with internal carotid artery stenosis

Three different strategies should be associated for ischaemic stroke prevention in patients with internal carotid artery stenosis: vascular risk factors control, anti-thrombotic agents, and carotid revascularization. Patients are selected for carotid revascularization on the basis of the presence of clinical symptoms and degree of stenosis. The optimal indication for carotid surgery is a severe recently symptomatic stenosis, since the benefits are marginal in high-grade asymptomatic stenosis, and in moderate symptomatic stenosis. Angioplasty with endoprothesis is an alternative to surgery, but it must be restricted to symptomatic stenosis either in randomized trials, or in severe stenosis in patients in whom surgery is contra-indicated.     

Indications for revascularisation of a carotid stenosis

TO PREVENT ISCHEMIC STROKE: Three types of measures should be taken: correction of the vascular risk factors, administration of antithrombotic agents and carotid revascularisation in patients selected on the basis of clinical and imaging criteria. CAROTID REVASCULARISATION MEASURES: The optimal indications are carotid surgery for severe symptomatic stenosis, while the benefits are marginal in severe asymptomatic stenosis and in moderate symptomatic stenosis. INDICATIONS FOR PERCUTANEOUS ANGIOPLASTY WITH PLACING OF AN ENDOPROSTHESIS: Angioplasty with endoprosthesis, a possible alternative to surgery, must be restricted to symptomatic stenosis either in randomised studies or in severe stenosis in patients in whom surgery is technically contraindicated.     

Management of atherothrombosis with clopidogrel in high-risk patients with recent transient ischaemic attack or ischaemic stroke (MATCH): study design and baseline data

BACKGROUND: The CAPRIE study showed the superiority of clopidogrel over acetylsalicylic acid (ASA) for reducing the combined risk of major atherothrombotic events in patients with recent myocardial infarction (MI), recent ischaemic stroke (IS) or established peripheral arterial disease. The benefit of clopidogrel over ASA is amplified in high-risk patients. Proof of concept for the benefit of clopidogrel in addition to ASA in patients with coronary manifestations of atherothrombosis was provided by the CURE trial. METHODS: MATCH is a randomized, double-blind, placebo-controlled trial that compares clopidogrel and ASA versus clopidogrel alone in high-risk patients with recently symptomatic cerebrovascular disease. Eligible patients have experienced a transient ischaemic attack (TIA) or IS within the last 3 months and have evidence of at least 1 additional risk factor within the last 3 years (prior IS, MI, stable or unstable angina pectoris, diabetes or symptomatic peripheral arterial disease). Patients were randomized to receive ASA 75 mg once daily or placebo, with both groups receiving clopidogrel 75 mg once daily as part of standard therapy. The primary end point is the composite of IS, MI, vascular death and rehospitalization for an acute ischaemic event. The duration of treatment and follow-up is 18 months for each patient. RESULTS: Enrollment was completed in April 2002, with 7,599 patients randomized to receive the study medication. The mean age at randomization was 66 years, and the qualifying event was IS in 78.9% of patients and TIA in 21.1%. The baseline features of the study cohort indicate a population that is at a high risk for atherothrombotic recurrence. CONCLUSION: MATCH is a major ongoing trial that will provide important data on the benefit of clopidogrel and ASA compared with clopidogrel alone for reduction of vascular ischaemic events in patients with recent TIA or IS who are at high risk of atherothrombotic event recurrence.
